Modern gadgets have become an integral part of our lives. The phone is the most common gadget. Almost every person has it. Unfortunately, even the most reliable phones can break due to shock, water or software glitches. The most common problem that many mobile device users face is that the sensor does not respond to touch. If the device is still under warranty, then you should immediately contact the service center. Otherwise, do not rush, because there are times when the problem can be easily and quickly fixed. The sensor does not respond to touch, what should I do in this case? Let's look at all aspects of this problem.
Phone Screen Repair
Before solving the problem, you need to make sure what is the cause of your display failure. This may be mechanical damage, liquid getting inside the device, or a software failure. If you are sure that you are notdropped the phone or spilled liquid on it, then we can assume that this is a software failure.
Mobile phone screen cleaning
First, you can just clean the display of your device. You will not harm the phone in any way, but improve the connection and perhaps the problem will be solved. This method can help if the sensor does not respond to touch. What to do?
We take a suitable cloth and liquid to clean the screen. It is better to use a lint-free or any other natural fabric. To clean the display, we'll need eyeglass or monitor cleaner.
If this method did not help, then you should proceed to the next steps. Of course, they can't help either. Only a professional can determine the true cause of a breakdown, but even he can not solve every problem.
Software glitch resulting in display failure
If the display of the mobile device sometimes reacts to your touch, then you can try to make a Hard Reset of the system, this is a complete reset. But it is worth remembering that this can only help if the sensor is buggy from time to time. After resetting the settings, install applications that can clean the system registry. This will eliminate errors caused by RAM. Recommended applications are WinFixer and Cleaner4. Unfortunately, the second utility is paid, but has good functionality. The first program is for you if you are unsure of the reason why the display is not responsive to touch and you are not going to spend money.
All actions should be done without a memory card. It may contain viruses that cause system malfunctions. After resetting the settings and cleaning the registry, you need to put the SD card back in place and check the device with an antivirus. Select full device scan and wait. But even after the actions taken, the sensor does not respond to touch. What to do? In this case, it is necessary to move on to replacing the sensor, since the cause is not caused by a software failure.
Mobile phone display replacement
The sensor does not respond to touch - what should I do? If the previous methods did not help, then you need to change the damaged display. Most often, this should be done when the device has fallen, cracks have appeared, or moisture has entered. In the latter case, you may not even notice how liquid got into the phone, as this can happen due to temperature changes. So, the condensate that accumulates in a mobile device will interfere with the normal operation of the phone. At first, black spots may appear when working with the gadget, and later the sensor itself will stop responding to touch. In this case, you will need to change the screen.
Repairing a phone screen is not a very complicated process, the main thing is attentiveness and accuracy. This can be done by anyone. The sensor does not respond to touch - what to do? First you need to disassemble your device, but you should remember the sequence of actions so that there are no problems with assembly in the future. All plugs and latches are removed with a thin object. You will need to carefully remove all elements fromlatches.
After disassembling your smartphone, you need to remove the display. It is necessary to check how the display is attached to the matrix. This can be done in two ways: monolithic or separate. This is very important, as this aspect will need to be specified when ordering a new screen.
The sensor can also be connected to the PCB in various ways. There is a contact method, while the sensor is simply disconnected, and wired. In the latter case, you should be very careful.
If you need to detach the matrix from the sensor, you must follow these recommendations:
- First preheat the surface to 60 degrees. This can be done with a regular hair dryer. It should be heated evenly so that the glass does not crack, and the glue heats up.
- Next, you need to find a flat and thin object to easily detach the sensor from the matrix. To do this, simply pry off the edges and gently lift.
It remains only to attach a new sensor. How to do it? The kit should include the sensor itself and glue. First, we apply special glue, and then carefully attach the sensor.
Cost of a new display
How much does a touch screen cost? Of course, the cost of the screen will differ for different models of smartphones. On average, to change the display on phones with a diagonal of 4, 5 or 5 inches, you will need to pay about 700 rubles.
If you do not want to disassemble the phone yourself, you can contact a specialist. For replacing the touchscreen, the master will ask about 2000 rubles. Although this procedure is not very complicated and you can change the screen yourself. Only this will need to be approached carefully and carefully.
Touch buttons do not work
The bottom touch buttons are directly related to the screen and in case of their failure, you must do all the actions that we have already considered. If the touch buttons do not work, you should first do a full reset. Next, clean the system registry and check your device for viruses. Unfortunately, if the steps taken do not help, then it will be necessary to change the screen.
